IMPROVEMENT IN HEMMERS FOIR SEWING-MACHlNES.

Specification forming part of Letters Patent No. 124,809, dated March 19, 1872.

SPECIFICATION.

I, HARRYAC. GoonRIoH, of the city of Ghicago, in the county of Cook and State of Illinois, have invented certain 4new and useful Hemmer `forSewing-Machines, of which the following is a full description, reference being had to the accompanying drawing making a part-of this specification, in whichj Figure ll-is a perspective; Fig. 2, a bottom 1 view; Fig. 3, a side view'5'I1`ig. 4, a cross-section on linewx and Fig. 5, blank from which `the convolute plates are formed.

In'the hemmers having convoluted springs, when the, cloth from any cause works out it A is very difficult to replace it without taking the cloth entirely ont, and commencing again at the back end of the springs.

My invention overcomes `this difficulty; and it consists in using a plate constructed ashereinafter described, and connected to a plate secured-to the presser-foot, and withmy device there. is

no more pressure on the clothV at the point than there is 'at the heel of` the hem-turner, the plates being equidistant from each other at all points'. f

In the drawing, a represents the main vor baseplater; b, the convolute-plates; c, the bent shaft or foot; d, hole; e, screw forconnecting 'the shaft c with the presser-foot of a sewingmachine; f, projection at lower end of c g, connection between the points of the plates b,- and h, twisted portion ofthe plates. The parts a c d are made as shown, and in the usual wellclothworks out when in operation it can easily and readily be replaced. The cloth passes so easily and smoothly through this hemmer` th at it can be used for any width of hem without change.

What I claim as new is as follows: 'Ihe hemmer, composed of the slotted plate Vb twisted on itself, as shown, the slotted plate a., to which it is connected, and the presser-foot,

all being constructed and arranged to operate substantially as described. HARRY C. GOODRICH.
